Disclosed are a solid-state imaging apparatus, a signal processing method of a solid-state imaging apparatus, and an electronic device, which are capable of correcting uneven sensitivities generated by multiple factors in a broad area and realizing the higher-precision image quality. A correction circuitweight a sensitivity Pi corresponding to a pixel signal of each pixel related to correction in a pixel unit PU that is the correction target and a sensitivity Pi corresponding to a pixel signal of each pixel related to correction in at least one same color pixel unit PU and adjacent to the pixel unit PU that is the correction target by a weighting coefficient Wi. Consequently, the correction coefficient &#x3bc; is calculated by dividing a sum of the weighted sensitivities by a total number n of pixels related to correction.

Solid-state imaging apparatus, signal processing method of solid-state imaging apparatus and electronic device

An optical sensor includes a substrate, a light emitting element, a light receiving element, and an electronic circuit element. Light from the light emitting element is blocked by a detection object to detect the detection object. The light emitting element, the electronic circuit element and the light receiving element are mounted on the same surface of the substrate. The electronic circuit element is disposed between the light emitting element and the light receiving element on a mounting surface of the substrate.

Optical sensor

An optical sensor includes a bare chip mounted on a circuit board, a protection member configured to protect the bare chip, a pad connected to the bare chip via a wire, and a pattern connecting the pad and a terminal portion at an edge of the circuit board to each other. The pattern is connected to the terminal portion on a same surface as a surface on which the bare chip is mounted, and a portion of the pattern between the protection member and the terminal portion is covered with solder resist.
